Okay, so Shepard Fairey's art involves defacing other people's property, sometimes with permission, sometimes without. He pastes his truly wonderful poster art on buildings, which are pieces of architecture, which is a form of art.

If he does this in Allston, people deface his posters. Tear out chunks and (since the shreds aren't scattered around the pavement, and we know nobody's ever swept that lot) keep them as souvenirs.

For a preview of the Celtics' impending run, this picture says it all, really. Garnett - whose mysterious knee injury will keep him out of the entire postseason - will sit on the bench. Danny Ainge - recovering from a mild heart attck - will be watching from a comfortable place.

A Celtics team without Garnett is still good enough to beat the Bulls on paper.

Tonight, playoff action begins for your Boston Bruins, and really, it couldn't come at a better time. We just found out that Kevin Garnett is probably going to be out for the duration of the Celtics' playoffs - and more on him tomorrow - and, of course, whenever things are going less than great for the Red Sox, people around here start getting cranky, justifiably or not - more on them coming soon, too. The Bruins have a chance to really seize this town's attention - for a time, at least.

Of course, it is hard to get people's attention in this town sometimes, and, you may have heard, the NHL hasn't had an easy go of it lately in general. We doubt we're alone when we say we haven't been following hockey too closely over the years. Fortunately, we know someone who has been paying attention: Globe reporter and friend of The Sandbox Chris Forsberg, who was kind enough to answer some of our novice questions. Our brief Q+A follows after the jump:

Last week, two young women were arguing about the color of zombies in a waiting room at Mass General. When a doctor appeared, they asked her for an opinion on whether zombies should, by rights, be green or gray. The doctor thought for a second and said, "I don't know, but I'll ask my friend Dr. Schlozman -- he's been driving us nuts all week trying to get us to watch zombie movies."

If an afternoon perfecting the art of Medieval Carpentry sounds to you like time well spent, you should probably be at the seventh-annual Boston Skillshare at MIT this weekend. Run by an entirely-volunteer organizing collective, the two-day event features workshops ranging from the somewhat esoteric (“Wild Carrot as a Natural Method of Contraception,” “Making Milk out of Nuts and Seeds,” or “Spoon Carving”) to the practical (the simply-titled “Time Management”).

As I was just reminded via email by my buddy Alex Zaitchik, there are a lot of Irish people in Boston. Sure - these days most of them are more yuppie than rogue - but they're Irish nonetheless. On that note: folks might appreciate the piece that Alex just did for The Nation about a town of Irish farmers who went head-to-head with Shell and other oil interests that want to run a pipeline through their county.

Shepard Fairey could face jail time for his, ahem, alleged graffiti in Boston after a Municipal Court judge decided yesterday that the vandalism charges against him could be treated as felonies instead of misdemeanors.

The Los Angeles artist, whose work is the focus of a major retrospective at Boston’s Institute of Contemporary Art, faces as many as a dozen charges from Boston police.

When the Chez Vous roller rink has run into money problems in the past, there have never been specific culprits. In fact, such situations have yielded heroes, like this past year when Mayor Tom Menino and several labor unions helped owner Greer Toney install a costly sprinkler system.

But this time – with the landmark staving off foreclosure one minute at a time – there’s someone very specific to blame.

So this new ad for the pube-friendly Schick Quattro - in which the euphemism for bush shaving is “mow the lawn” - is raising several questions: how come Brits lose their accents when they sing; why does England get all the good commercials; and, of course, is this spot offensive to women?

Over the past few months, quite a few observers of right-wing nutjobs have been having some fun with Fox News host Glenn Beck, whose ranting and raving has taken on an increasingly deranged tone. Just this past week, for example, he simulated dousing someone with gasoline to make a point about how Barack Obama may as well just light the "common man" on fire rather than subject us all to his policy.
